| Term | Definition |
|---|---|
| Inorganic | no carbon |
| Acids | release hydrogen ions when dissolved in water(0-6 on the pH scale) |
| Bases | release hydroxide ions when dissolved in water(8-14 on the pH scale) |
| pH Scale | a way to measure how acidic or basic a chemical is |
| Organic | contains carbon as the major component |
| Carbohydrates | sugars! immediate energy source |
| Monosaccharides | simple sugars |
| Disaccharides | double sugars formed by 2 monosaccharides joining together by dehydration synthesis. (protein key) |
| Polysaccharides | polymers (long branching chains of linked monosaccharides) linked together by dehydration synthesis. (large & fairly insoluble which make them ideal storage products) |
| Hydrophilic | likes water |
| Hydrophobic | dislike waters |
| Neutral Fats - Triglycerides | long term energy storage no oxygen does not dissolve in water |
| Phospholipids | cell membrane structure dissolves in water |
| Steroids | Hormones made my cholesterol |
| Proteins | structure, enzymes, regulation |
| Amino Acids | building blocks of proteins (2 types: fibrous and globular) |
| Peptide Bond | primary structure of proteins |
| Isotonic Solutions | same solution |
| Hypotonic Solutions | more water |
| Hypertonic Solutions | less water |
| Mitosis | cell division |
| Cell Physiology | DNA makes RNA RNA makes Protein |
| DNA | Deoxyribose Nucleic Acid (hereditary material) |
| RNA | Ribose Nucleic Acid (controls protein structure) |
| ATP | Adenosine Tri Phosphate (energy molecule) |
| Diffusion | the spreading of particles from an area of higher concentration to an area of lower concentration |
| Osmosis | diffusion of water |
| Cytokinesis | cytoplasm division |
